RELATED APPLICATION

This application claims priority to U.S. Provisional Patent Application Ser. No. 60/969,419, filed Aug. 31, 2007, the entirety of which is hereby incorporated by reference.

TECHNICAL FIELD

The present disclosure relates generally to voicemail and, more particularly, to providing a voicemail password reset feature.

BACKGROUND

Voicemail systems allow a caller to leave a voice message if the desired recipient is unavailable. Traditional voicemail systems (referred to herein as plain old voicemail or POVM) allow a subscriber to place a call to a voicemail system to access messages stored in his or her voicemail box. This is done through a telephone user interface (TUI) that facilitates interaction between the subscriber and the voicemail system. The TUI provides functions for the subscriber to listen to messages, skip messages, delete messages, and save messages. The TUI can also provide functions for the subscriber to set a voicemail greeting, record a voicemail greeting, record a name, and set/change a password.

With some voicemail systems, a subscriber with multiple voicemail messages is required to listen to, skip, delete, or save each message while reviewing the voicemail box. This is time consuming and can be frustrating for the subscriber in situations where an important message has been deposited, requiring the subscriber to listen to, skip, delete or save each message in search of the important message.

To help reduce the need to search through multiple messages, various improved voicemail systems have been developed that allow messages to be stored based on a priority scheme to increase the efficiency of listening to voicemail messages. Often, these systems use a telephone number of the caller to identify a priority for a message and position the voicemail messages in order based on the assigned priorities. When the recipient accesses the voicemail system to acquire voicemail messages, the recipient is presented with each voicemail message in order of the priority or importance to the recipient. This reduces unwanted listening or skipping through multiple voicemail messages to find an important message. However, an important message can easily be relegated to a position of low importance if the subscriber has not previously set the priority for the caller. In this system, the priority for an incoming voicemail message is determined directly by the telephone number associated with the caller.

The aforementioned systems often fail to allow a subscriber to select the exact voicemail message the subscriber would like to hear. Further, the aforementioned systems require the use of a TUI to access the voicemail system to listen to voicemail messages and manage a voicemail account. Still further, these systems merely notify a subscriber of a pending voicemail message with a message waiting indicator (MWI) and require that the subscriber access the voicemail system to retrieve the pending message(s).

Thus, it is desirable to create new enhanced voicemail systems and novel methods for providing visual voicemail (VVM) services. Moreover, there is a need to be able to reset a voicemail password directly from a subscriber's mobile device.

SUMMARY

DETAILED DESCRIPTION

As required, detailed embodiments of the present disclosure are disclosed herein. It must be understood that the disclosed embodiments are merely exemplary examples of the disclosure that may be embodied in various and alternative forms, and combinations thereof. As used herein, the word “exemplary” is used expansively to refer to embodiments that serve as an illustration, specimen, model or pattern. The figures are not necessarily to scale and some features may be exaggerated or minimized to show details of particular components. In other instances, well-known components, systems, materials or methods have not been described in detail in order to avoid obscuring the present disclosure. Therefore, specific structural and functional details disclosed herein are not to be interpreted as limiting, but merely as a basis for the claims and as a representative basis for teaching one skilled in the art to variously employ the present disclosure.

Referring now to the drawings wherein like numerals represent like elements throughout the several views, FIG. 1 schematically illustrates a portion of an exemplary wireless communications network 100 in which embodiments of the present disclosure can be implemented. By way of example, the wireless communications network 100 can be configured as a 2G GSM (Global System for Mobile communications) network and can provide data communications via GPRS (General Packet Radio Service), and EDGE (Enhanced Data rates for GSM Evolution). By way of further example, the wireless communications network 100 can be configured as a 3G UMTS (Universal Mobile Telecommunications System) network and provide data communications via the HSPA (High-Speed Packet Access) protocol family, such as, HSDPA (High-Speed Downlink Packet Access), EUL (Enhanced Uplink) or otherwise termed HSUPA (High-Speed Uplink Packet Access), and HSPA+ (Evolved HSPA). The wireless communications network 100 is also compatible with future mobile communications standards including, but not limited to, pre-4G and 4G, for example. The wireless communications network 100 can be configured to provide messaging services via Short Message Service (SMS), Multimedia Message Service (MMS), instant messaging and unstructured supplementary service data (USSD), for example. The wireless communications network 100 can also be configured to provide advanced voicemail messaging features, such as visual voicemail.

The illustrated wireless communications network 100 includes a voicemail system (VMS) 102 that is illustrated as being in communication with a content delivery server (CDS) 104 and an unstructured supplementary service data (USSD) server 106. The VMS 102 can include a telephony server (TS) 108 for handling incoming voicemail inquiries via a telephone user interface (TUI) 109 and a storage server (SS) 110 for storing and managing voicemail messages for a plurality of voicemail accounts. The USSD server 106 can be configured to receive, decode, and process new USSD messages; perform database queries to retrieve the VMS hostname serving a subscriber; perform database queries to resolve the VMS hostname to the corresponding IP address; obtain the subscriber's voicemail class of service (COS); and send the subscriber's voicemail COS to the subscriber's mobile device. The USSD server 106 is illustrated as being in communication with a home location register (HLR) 112, a subscriber database 114, and a domain name server (DNS) 116 to facilitate these functions. The USSD server 106 can be further configured to handle a password reset request message received from the MD 118. A password reset request message can be used to reset a voicemail password directly from the MD 118 without the need to call the VMS 102 via the TUI 109. The MD 118 can be, but is not limited to, a user equipment, a mobile terminal, a cellular telephone, a personal digital assistant (PDA), a handheld computer, or combinations thereof, and the like.

The subscriber database 114 can be configured to store and manage subscriber data, such as, for example, account information, billing information, services information, and equipment information for a plurality of subscribers. The DNS server 116 can be configured to maintain a database for resolving host names and IP addresses for various network nodes, such as the VMS 102, for example. The USSD server 106 can retrieve the VMS hostname serving a subscriber from the subscriber database 114 and query the DNS 116 by specifying the VMS hostname to resolve the corresponding IP address.

The HLR 112 can be configured to provide routing information for mobile-terminated calls and short message service (SMS) messages. The HLR 112 is illustrated as being in communication with a mobile switching center (MSC) and visiting location register (VLR) 120. The MSC/VLR 120 is in communication with the MD 118 and a short message service center (SMSC) 122. The SMSC 122 can be configured to delivery SMS messages and message waiting indicator (MWI) messages.

The VMS 102 can be configured to store a plurality of voicemail accounts. Each voicemail account can include a voicemail box in which voicemail messages can be deposited for a subscriber. The number of voicemail messages capable of being stored per account can be determined by the voicemail service provider or any third party provider, such as the system manufacturer, for example. The maximum voicemail message length can also be set. The number of voicemail messages and the maximum voicemail message length can be configured on the VMS 102.

Prior to a subscriber being provisioned for visual voicemail service, the voicemail box is in a not provisioned state. After being provisioned for visual voicemail service, the subscriber's voicemail box state is changed to provisioned—not initialized to reflect that the subscriber is provisioned for service but has not yet initialized service via a boot message process described later with reference to FIG. 3. After completion of the boot message process, the VMS 102 state can be changed to provisioned—initialized to reflect that the subscriber is provisioned for voicemail service and has completed the first boot access process.

The VMS 102 is accessible via traditional or plain old voicemail (POVM) methods and visual voicemail (VVM) methods described herein. State changes to voicemail messages, whether requested through TUI via POVM methods or directly on the MD via VVM methods, are automatically updated in both the voicemail box and on the subscriber's MD 118. This ensures automatic and full synchronization between the subscriber's MD 118 and the VMS 102 so that the latest voicemail information is stored on the subscriber's MD 118. The subscriber's VMS-hosted voicemail box recognizes and maintains message states for each message such as, but not limited to, an unheard—new state, a skipped state, and a saved—read state. Deleted messages can be deleted from the VMS 102, via the TUI or directly on the MD 118. The message is deleted on both the VMS 102 and the MD 118. However, in an alternative embodiment, deleted messages remain accessible on the MD 118 and/or on the VMS 102 for a specified period of time to allow the message to be recovered in the case of accidental or premature deletion. In other embodiments, the VMS 102 discards all messages after the MD 118 has successfully received and stored the available message content.

The MD 118 voicemail box also recognizes and maintains message states. The MD 118 voicemail box can have message states for each message including, but not limited to, an unheard—new state, a saved—read state, and a deleted state. The MD 118 does not require a skipped state because WM provides an interface that allows a subscriber to access any message regardless of the order in which the message was received and is not subject to restraint of a priority scheme. As mentioned above, the MD 118 voicemail box deleted state can be configured such that the message is available for recovery or merely as an indication that the message has been deleted. Either of these options can be set to be available for a time specified by either the subscriber via a device input or by the voicemail service provider.

Referring now to FIG. 2, an exemplary message flow diagram illustrates a process 200 for handling a password reset request, according to the present disclosure. In the illustrated process 200, messages are sent using a variety of protocols, such as short message peer-to-peer (SMPP), domain name server (DNS) protocol, lightweight directory access protocol (LDAP), unstructured supplementary service data (USSD) protocol, Internet message access protocol version 4 (IMAP4), and hypertext transfer protocol (HTTP), for example. The description provided below assumes an understanding of these protocols and as such further explanation is not provided. The use of alternative protocols or additional protocols to acquire similar results is deemed to be within the scope of the present disclosure. Accordingly, logical variations of the illustrated message flow are contemplated.

In step 202, the mobile device 118 generates a password reset request message and sends the password reset request message to the HLR 112. It should be noted that, in the illustrated embodiment, the password reset request message is a USSD message, however, other message such as, for example, an SMS message are contemplated. The HLR 112 receives the password reset request message and appends the mobile subscriber ISDN number (MSISDN) to the password reset request message, in step 204. In step 206, the HLR 112 sends the password reset request message with the appended MSISDN to the USSD server 106. The USSD server 106 receives the message and submits an LDAP query to the subscriber database 114 to determine the hostname of the VMS 102 (VM ID) serving the subscriber, in step 208. In step 210, the subscriber database 114 responds with the proper VM ID. In step 212, the USSD server 106 sends a DNS query to the DNS server 116 to obtain the IP address corresponding to the VM ID. The DNS server 116 resolves the IP address from the VM ID and submits a DNS query response to the USSD server 106 with the IP address for the VMS 102, in step 214. In an alternative embodiment, the IP address for the VMS 102 can be obtained by a data table provisioned on another network element, such as the CDS 104, for example.

If no VM ID is found, the subscriber is not provisioned for voicemail service and the USSD server 106 generates a message to this effect which is sent to the SMSC 122, in step 216. The SMSC 122 receives the message and generates a short message (SM) to be sent to the MD 118 to inform the subscriber of the condition, in step 218.

If a VM ID is found, the USSD server 106 sends a password reset request message to the VMS 102, in step 220. In step 222, the VMS 102 receives the password reset request and resets the password to a new default password. The VMS 102 also generates a boot message request and sends the request to the SMSC 122, in step 224. The boot message request instructs the SMSC 122 to prepare a boot SM including the new default password (reset password). In step 226, the SMSC 122 generates a boot message including the default password and sends the boot message to the MD 118, in step 226. An exemplary boot message is described now with reference to FIG. 3.

Referring now to FIG. 3, a message flow diagram of an exemplary process 300 for handling a boot message in response to a password reset request is illustrated, according to the present disclosure. The process 300 assumes that the subscriber has been provisioned for VVM service and has the proper voicemail class of service (CoS) for visual voicemail. When the subscriber is initially provisioned to the VMS 102 with a VVM CoS, the subscriber's account can be enabled for voicemail notification via the CDS 104. The VMS 102 can initiate a notification message to the CDS 104 that is intended for delivery to the subscriber's MD 118 via a short message peer-to-peer (SMPP) message. This enables the subscriber to have confirmation that the VVM service is enabled and to immediately access the service via a VVM application. A visual prompt can be presented to the subscriber as a cue or reminder to setup a voicemail box prior to receipt of incoming voice messages. Conventional voicemail, in contrast, blocks receipt of new messages until the mailbox is set up, or notifies the subscriber of the first new voice messages thereby prompting the subscriber to place a call to retrieve them, but bars access to those messages until the subscriber sets up the mailbox. The visual prompt of the present disclosure advantageously eliminates the annoyance and need to access the VMS 102 via the TUI 109 to setup the voicemail box and ensures the subscriber sets up a voicemail box. The notification message can also be used to reset a voicemail password after a voicemail account is enabled.

The WM service uses several parameters to enable automatic synchronization between the MD 118 and the VMS 102. For example, prior to first boot, the MD 118 does not have the CDS ID, port number, mailbox ID, initial or reset password, and a token value, if applicable. Accordingly, the process 300 described below provides an initial SMPP message including a basic set of parameters for future synchronization sessions including a default password. If a subscriber forgets the password or otherwise needs to have the voicemail password reset, the subscriber can initiate the process 200 described above with reference to FIG. 2 by selecting a password reset option on the MD 118. In this example, a new boot message can be sent to the MD 118 including a new default password in response to a password reset request from the MD 118.

The process 300 begins when the VMS 102 generates an SMPP notification message (notificationSM), in step 302. For example, a notification SM message can include, but is not limited to, the hostname and port number for the subscriber's CDS 104, a token identifying the subscriber's VMS 102, the subscriber's voicemail box ID (mailbox ID) embedded with the token to uniquely identify the subscriber for the VMS 102, and a default password. In an alternative embodiment, the notificationSM can include the IP address and port number for the subscriber's CDS 104 and the mailbox ID. The password and token can be added to increase security and preserve data integrity. If a password is used, the password may be unencrypted and the password can be obscured to hide the actual default password digits.

After the notificationSM message is generated, the VMS 102 can send the message to the CDS 104, in step 304. In step 306, the CDS 104 can receive the notificationSM message and generate a VVM application directed notificationSM message and send the message to the SMSC 122. The SMSC 122 can receive the message and forward the message to the MD 118, in step 308. The application directed short message can be received by the MD 118 and sent directly to the WM application. The WM application can inform the subscriber of the new default password.

For situations in which VVM is temporarily unavailable for network maintenance, device maintenance, or other unforeseen circumstances, the VVM subscriber can access voicemail messages via the VMS 102 (e.g., via the TUI 109) as a default access method.

FIG. 4 is a schematic block diagram illustrating an exemplary mobile device 118 for use in accordance with an exemplary embodiment of the present disclosure.
